GAS CooKlNG APPARATUS.

SPECIFECATION forming part of Letters-Patent No. 683,331, datedSeptember 24, 1901.

Application filed December 14, 1900. Serial No. 39,855. (No model.)

To all whom, it may concern:

Be it known that I, EDMOND W. T. RICH- MOND, a subject of the Queen ofGreat Britain, residing at Summercourt, Romford, Essex county, England,have invented certain new and usefullmprovements in Gas CookingApparatus, of which the following is a specification.

This invent-ion relates to a separable, supplementary, or additionaloven adapted to be placed within the oven of a gas eookingstove. It isapplicable to that class of eookersin which the burners are located atthe bottom of the oven.

In the drawings is shown a gas-cooker having a single ratherhigh ovenlike or similar to that disclosed in my application, Serial No. 39,854,iiled December 14, 1900. The oven of such a cooker may have a burner atthe top, two bottom burners at the sides, and one bottom burner at therear. The supplementary oven herein discolsed is designed to coperatewith the bottom burners and preferably with the side ones only. It is soconstructed as to be adapted to be placed in the oven of the cooker, inthe lower part thereof, when desired for the baking of some article offood, as bread or biscuit, not requiring the heating and use of theentire oven and may readily be removed. While the supplementary oven isin use the upper part of the oven may be utilized for some otherpurpose.

In the accompanying drawings, Figure l is a vertical transverse sectionthrough a gascooker having a single relatively high oven containing oneof my supplemental ovens; Fig. 2, a perspective view of one form of thesupplementary oven g Fig. 3, a like view of another form capable ofbeing knocked down or folded up, and Fig. 4. shows the latter ovenfolded.

Figure 1 indicates a gas-cooker having double walls X Y, the interveningspace between which is to be packed with mineral Wool, ,asbestos, orother suitable heat-insulating material.

A is a cast-iron false top through apertures in which the products ofcombustion pass, and thence between A and the cover B to the outlet C.The burner D beneath the false top, supplied with gas from the gas-bar Ethrough the nipple e and taking air around the nipple, may be used forgrilling.

The runners or ways in or on the sides ff of the oven for supporting thegrids orshelves for the cooking utensils are shown in Fig. l. On the topof the casing at each side is a bracket G, which supports the hot plateor upper frame in which grilling and boiling burners are mounted, all asis well understood. At the bottom of the oven three burners aresh0wn,one,H,at`the right side,another, I, at the left side, and a third,K, at the rear, all to be supplied with gas and air, as is wellunderstood. The upper burner is shown as removably mounted,and the otherthree burners may be similarly mounted.

The supplementary oven is composed of a rear wall 2, side walls 3 4, anda double top 5 6 and is open at the bottOm and front. The inner faces ofthe side Walls are provided with runners or ways to receive grids orcooking-pans. The products of combustion pass out at the top throughapertures in the plate 6, and thence through the apertures in the plate5. The apertures in the two plates are staggered or non-coincident, soas to retain for a time the products of combustion between the platesand keep the top of the oven warm. This subsidiary oven may be passedthrough `the oven-door and into the position shown in Fig. l, in whichthe rear Wall 2 is in `front of the rear burner K and the side walls 3fl rest on the burners H I. To afford a suitable and appropriate basefor the supplementary oven, the burners H I, which are of cast-iron, areformed with dat tops 7L t' and a vertical rib or flange h t" along theouter edge. Such an oven may readily be slipped into place and withequal facility removed when the required purpose of its use isaccomplished.

For the convenient stowage of the supplementary oven, either fortransportation or in the household, it is constructed as shown in Figs.3 and 4. The side 3 is hinged at s s to the upper edge of the doubletop-t1 e., to the edge of the plate -and may be folded over upon thetop. The side e is hinged to the back plate at t t and may be foldedback upon it, when the double top may be folded down upon the face ofthe back plate. The

IOO

back 2 is hinged to the part 6 of the top at s.

The oven wheny so foldedv is shovm inFig. 4.'

in the drawings and briey described and made in somewhat different formWithout de` parting from the spirit of the invention.

I claim as my inventionl. The combination with a fixed or stationarygas-cooker oven and a supplementary oven therein,l and removabletherefrom, comprising top, rear and side Walls,'and open at front andbottom, and having an oven-space above the top thereof in thecooker-oven, a gas-burner for heating the main oven, karranged outsideof the supplementary oven, and a gas-burner discharging into thesupplementary oven.

2.' `The combination with a gas-cooker oven, of asupplementary oventherein, and removable therefrom, comprising top, rear and sidev walls,and open at front and bottom, and provided Witli an oven-space above itin the cooker-oven, a gas-burner arranged at the top of said space inthe cooker-oven, and gasburners arranged at the bottom of thesupplementary oven and discharging thereinto.

3. The combination of a 'fixed or stationary gas-cooker oven and asupplementary oven arranged therein, having a space. between its rearvend andthe back of the main oven, and

space on each side thereof, as well as a large oven-space above it inthe main oven, gasburners discharging directly into the open bottom ofthe supplementary oven, a gasburner in rear of the supplementary oven,discharging directly into the main oven, and a gas-burnerat the top ofthe main oven.

f4. The combination of a gas-cooker oven, of the bottom side burnersformed With seats lon their upper surfaces to receive the lower edges ofthe side walls of a supplementary oven, and la supplementary oven withinthe main oven open at front and bottom, and having top and side walls,the latter of which rest upon the seats of the side burners.

5. A supplement-ary oven for gasfstoves having a double top with onesidehinged to the top so as to fold over upon the upper surface thereofaback hinged to the top so as to fold over the inner surface thereof,and another side hinged to the back so as to fold over upon the outerside thereof.

In testimony whereof I have hereunto subscribed my name.
